Sure! Here's an example of a simple 3D shooting game where you can shoot zombies. Please note that this is a simplified version and might not have all the advanced features you would find in a complete game.
To play the game, you can copy and save the above code in an HTML file (e.g., `zombie_shooter.html`) and open it in your web browser. Use the arrow keys to move the player and press the spacebar to shoot bullets at the zombies. The objective is to survive as long as possible while shooting the approaching zombies. Score increases by shooting zombies successfully, and the game ends if a zombie collides with the player.
